My brother loves travelling around the UK. He ... 1900 kilometres, from Land's End, in the south of England, to John O'Groats, in the north of Scotland.

He ... by bus, car, train and horse, but he ... anywhere because he can't ride a bike! I ... him on his trips because I'm still at school, but I ... at his photos and they're really cool!
